Problems solved by technology

And the existing adhesive has the following problems: a. The peel strength is low or high. When the peel strength is low, when the glued row nails are cut off in the cutting process, or the manufactured row nails are packed, transported, etc. When the peeling strength is high, the nails are firmly bonded and cannot be driven out in a nail gun, which is difficult to meet the needs of high-end manufacturing companies; b. The drying speed is slow, which reduces the production efficiency of the nails; c. The storage stability is poor, and the storage period is generally about 6 months

Abstract

The invention discloses a metal strip nail adhesive and a preparation method thereof, and relates to the technical field of adhesives based on resin. The metal strip nail adhesive comprises the following raw materials in percentage by weight: 8%-16% of carboxyl vinyl chloride-vinyl acetate resin with average molecular weight about 34000, 0%-8% of carboxyl vinyl chloride-vinyl acetate resin with the average molecular weight about 27000, 3.5%-5.5% of nitrile rubber, 4.5%-6.5% of epoxide resin, 2%-4% of methylhexahydrophthalic anhydride, 0.01%-1% of aluminium acetylacetonate, 0%-40% of methyl acetate and 30%-77% of acetone. The metal strip nail adhesive is prepared through pretreatment, mixing, heating and stirring. The metal strip nail adhesive disclosed by the invention has the characteristics of moderation in stripping strength, fast drying, stability in storage and easiness for operation; a strip nail adhered through the adhesive can not be cracked when being cut in a cutting procedure, or a manufactured strip nail can not be cracked when being encased and transported; and the strip nail is easy to shoot in a nail gun, high in nailing efficiency and increased in production efficiency.

Description

Technical field [0001] The invention relates to the technical field of resin-based adhesives. Background technique [0002] Row nails are a new type of woodworking nails that are used to bond regularly arranged single nails with adhesive or other methods. The row of nails is put into a special nail gun, powered by electricity or compressed air, and shot into wood, plastic, or other composite materials through impact. The nail gun is widely used in construction, decoration, furniture, packaging, advertising decoration, decoration, sofas, leather shoes, leather goods, etc. because of its high efficiency, uniform and consistent force of the nails, and convenient use. There is also a large demand for "bullet" row nails. It will replace small iron nails, artificial decoration, decoration and other aspects of nails. [0003] The general production process of the row of nails is as follows: the round wire is straightened and squashed by a flattening machine, and assembled on a certain ...
